Abstract: A fixture can include a housing, a member for positioning the housing on or proximate to a surface in a room, an augmented reality (AR) target coupled to the housing and having a unique identifier for detection by an AR software application, and a light source disposed at least partially within the housing and configured to (i) illuminate the AR target for easier detection and (ii) at least partially illuminate the room. A method can include positioning the self-illuminated AR target in a possible position for an interior decoration in the room, initiating the AR software application on a mobile computing device, capturing image data including the self-illuminated AR target with the mobile computing device, and viewing an AR view of the room on a display of the mobile computing device, the AR view including an AR view of the interior decoration at the possible position.
